Abstract

A circuit breaker characterized by a pair of separable con­ tacts, one of which is carried by a movable contact arm, mov­ able within an arc chute having arc plates including a lower arc plate adjacent to the other contact. A link conductor leads to the other contact and electrically connected to the other contact.
